Idle Reset

[FOSHO94]

I read on another post that when you replace things like the MAF or O2 sensors its a good idea to "reset the idle". How would I go about doing this?

A quick search will yield plenty of topics on resetting the idle. Look for posts from sdpatt on this subject.

Glad you don't think I'm a **** for my response being, do a search! I know Scott has written up the details very accurately in the past and I wouldn't do it justice trying to replicate the details. Let us know if you can't find the procedure.

Someone else had posted these instructions:

NOTE 1: The Ford owner's manual directs that the idle program be relearned following any service when the battery has been disconnected. To do this, it states that the engine should be started and allowed to idle for the (approximately) 70 seconds without touching the gas pedal. Adding the accessory loads ensures that the EEC and IAC valve can accommodate the additional air flow requirements and still maintain the programmed idle speed.

NOTE 2: It is preferable that the car be driven immediately after setting the idle programming. While driving, allow the coolant temperature to rise to the normal range and run the car through its entire performance range.

Idle Speed Program Reset Procedure
-----------------------------------------
1) Disconnect the negative battery terminal.
....Optionally, disconnect the keep alive memory connector in the small wire also landed to the
....negative battery terminal. You can then wait the 10 minute minimum, reconnect the plug
....and go to step 6. I have found this option to not be as effective as disconnecting the battery.
2) Turn on the headlight switch.
3) Wait at least 10 minutes.
4) Turn off headlight switch.
5) Reconnect the negative battery terminal.
6) Start engine normally (never press the gas pedal).
7) Allow the idle speed to settle for at least 30 seconds.
8) Within 70 seconds of starting the engine, concurrently apply all accessory loads.
....a) Climate control to MAX A/C.
....b) Headlight switch ON, brights ON.
....c) Turn steering wheel slowly ~1/4 turn side to side.
....d) Press brake pedal.
....e) ATX SHOs only: shifter to DRIVE.
9) Do not turn off engine for at least 5 minutes.

yea, its not like I get mad when people tell me to do a search, I don't see why people get mad anyway, cause its a lot quicker, since you don't have to wait for someone to reply. Sometimes I just forget.

I have found this option to not be as effective as disconnecting the battery.

Why would this not be as effective?
